MOVABLE STORAGE-POCKET.-

SPECIFICATION forming part of Letters Patent Nol749,653, dated January12, 1904.

i I Application filed January 16, 1903. Serial No. 139,317. NO #10 191!)To (LU w/wm z't may concern:

Be it known that I, COLLINS ARNOL-D, a citizen of the United States,residing at Albany,

the following is a specification.

The invention relates to such improvements; novel construction andcombination of parts'hereinafter described and and it consists of thesubsequently claimed.

thereon, W tion.

Similar characters refer to similar parts in the several figures.

This invention is well adapted i'or usev libraries and stores where theupper shelves or pockets used to support books, dry goods,

or other commodities are beyond the reach of the attendant. v

The object of the invention is to provide means for moving the uppershelves or pockets up and down, so that when moved to a lower leveltheir contents are easilyaccessible and when moved to a high level theircontents.

are stored where the room occupied is less valuable on account ofitscomparative i'naccessibility.,

Theinvention consists in dividing the shelves other supports in theupperpart of astorage-case into movable sections or pockets,

providing a counterbalance common to a plurality of pockets andmechanism for moving the storage-pockets up and down one at a time andmaking the connections. between the pocket moved and the counterbalanceactive while the connections between the counterbalance and the otherpockets remain inactive, and means for regulating and controlling themovements of the various parts, as hereinafter more fully described andsubsequently claimed.

Referring to-the drawings, Figure 1 is a front elevation of an upperportion of a storage-case provided with my'improved apparatus with thefront of the incl'osure for the mechanism removed, showing thecross-partitions in section and showing'one of thestorand State of NewYork, have invented certain new and useful Improvements in MovableStorage-Pockets, of which the'mechanism being shown locked position.

Fig. 10 is acentral vertical section of the gov-' ernor mechanism, takenon thebroken line 10 10 in .Fig. 1. Fig. 11 is a vertical section taken on thebroken line 11 11in Fig. 1 look- 'ing in the direction of the arrow.

The storage-case 1 (shown in part only in the drawings) may extend thewhole length of one side of a room, being provided with shelv-' ing 2for the reception of books or other commodities, the upper portion beingdivided into sections or storage-pockets,-one of which, 3, is shown infull and in its normal upper osition, and another, 4, shownin part andsuspended at a lower level. The upper portion of. the storage-case isdivided into similar sections throughout its length. In the upperportion of the case-frame are provided suitable bearings forthe-'.rotary shaft 5, which may'e'xtend the cntireylength of thestorage-case. Upon this shaft are loosely-mounted drums 6, prefrotatedto wind the cable 7 upon shaft 9, thereby providing means for adjustingthe effective length of the cable, the toothed wheel being held in thedesired position by means of the spring-stop 11, secured to the upperend of the pocket, as shown. There are also mounted upon the shaft 5 twoor more drums 12, fixed by set-screws 14 to rotate with the shaft.Cables 15 have one end secured to one of these fixed drums and the otherend secured at 16 to a portion of the case-frame, the cables passingunder the counterbalancing-weight 20. The counterbalance is providedwith grooves 21, adapted to receive the cables.

As a means for actively connecting the storage'pockets' one at a timewith the counterbalance through the drums, cables, and drumsupportingshaft I provide for each loose drum a series of clips 22 on the shaft. Ihave shown inthe drawings four clips. The outside clip 23 most remotefrom the drum is provided with a hub 24:, which is fixed upon the shaftby the set-screw 25. The three clips between the fixed clip and theloose drum are loose upon the shaft; but each 'clip is provided with aprojecting lug 26. When all the pockets are located at their normalhighest position, (shown by the position of pocket 3 in Fig. 1,) thelugs of all the clips engage each other and also the projecting lug 27on the loose drums, as shown in Fig. 4, so that when a downward movementis imparted to any one pocket its cables communicate fa rotary movementto the loose drums in the direction of the arrow in Fig. 4, which drumsthrough the contacting clips communicate a similar rotary movement tothe shaft 5, upon which the clip most remote from the loose wheel isfixed, thereby imparting a rotary movement to the fixed drums andthrough them and the connecting-cables raising the counterbalance. Itwill be readily seen, however, that the loose drums connected with theother storage-pockets are not rotated, but remain stationary, becausethe rotary movement of shaft 5 rotates the most remote clip fixed to theshaft, which causes its lug to leave the contacting lug of itsneighboring loose clip until it has made almost a complete revolutionabout the sha ft, after which its lug engages the lug of its neighboringclip on the opposite side from that shown in Figs. 4 and. 5, and thecontinued rotary movement of the shaft and fixed clip imparts a rotarymovement to its neighboring clip, and another revolution of the shaft 5will rotate the neighboring clip until its lug has made a revolution onthe shaft and engages its neighboring loose clip, and so on, until allthe loose clips have been rotated, leaving the loose drums stationaryuntil the pocket has descended to its desired lowest point. The distanceto which any pocket can descend without rotating the loose drums of theother pockets will'depend upon the number of loose clipsinterposedbetween the loose drums and the fixed clip coac ting therewith, as wellas the size of the loose drums. Should it be desired to increase thedistance to which the storage-pocket may I be moved downwardly, it isonly necessary to insert another loose clip. The counterbalance whenmade in the form of a roll of heavy material, as lead, can be madecomparatively small in diameter. and extended the whole,

length of the storage-case o'r row of storagepockets, thereby occupyingavery small space behind the case, the weight being ef fective to balancea single storage-pocket, and by means of the mechanism above describedit is possible to make use of the entire weight of the counterbalancefor each pocket, the pockets being moved one at atime. When the loweredpocket is restored to its upper normal position, a reverse movement iscom-- munieated to the shaft 5 and the lug-clips until they are causedto resume the position shown in Figs. 4 and 5, with the lugs of theseveral clips all in engagement with each their normal position, wlnrebyanother-downward movement of the pocket would instantly communicate arotary movement to the shaft, so as to act upon the counterbalance.- Asa means for locking the other pockets in their normal position while onepocket is being moved from its normal position to a lower level Iprovide another series of lug-clips 30 (shown in Figs. 8 and 9,) one ofthe outer clips 31 being provided with a hub and set-screw 32, by whichthis clip can be fixed upon the shaft 5, and the other end clip 33with'an arm 34, connected by link 35. with a lever 36, fixed upon rotaryshaft 37, which runs parallel with the shaft 5 and is supported bysuitable bearings in the upper part of the case-frame. Fixed upon shaft37 by means of set-screw 38 is an arm 39, provided with hook 40, adaptedto engage with the pocket-supporting mech other and with the lugs on.the loose drums in anism of theremaining pockets and to hold vided atits oscillatory end witha right-angled. offset 47, having a seat e8adapted to receive oted at 46, Fig. 2,!to. the case-frame and proshaft 9and support the pockets in their nor- 1 mal positions, as indicated bydotted lines in Fig. 2. Each pair of arms adapted to sup port a pocketis provided with a connecting rod or shaft 9, which supports theguidepulleys 50. When a pocket is withdrawn from its normal position, ittravels in a circular path, the shaft 9'resting upon. the seat 48, Whilethe arm at swings from the vertical position (shown by dotted lines inFig. 2) to approximately the horizontal position. (Shown by solid linesin the same figure.) The shaft '9 does not leave its seat 48 until thecable t env gages the pulley 5O which'then acts as a guide ,plate 42,secured by bolt for the cable, allowing the pocket to descend in avertical line. VVhon the pocket is in its normal position, the shaft 49is very near the back of the case, as indicated by dotted lines in Fig.2, and the hook engages with this shaft 49 when any one of the pocketsis withdrawn from its normal position.

When desired, the hookearm 39 may also be provided with a latch 41,loosely mounted on shaft 37 and adapted to pass in between the shaft 49of the pocket-support and the 43 to the top of the pocket, the latch 41being provided with a depressed seat 44, adapted to support the shaft 49and prevent the pockets from accidentally being withdrawn when notpositively locked in position by the hook 40. The hook-arm is providedwith a lug 51, adapted to support the latch and prevent-the same fromdropping too low when the pocket is withdrawn and at the. same timeleaving the hook 40 free to close down upon shaft 49 when the latch 41'is in its supporting position. lines in Fig. 8.)

' To understand fully the operation of the locking mechanism shown inFig. 8, it should be remembered that the position of theparts shown inFig. 8 is the position assumed when all the pockets are in theirnormally highest position, the lug on the end elip.31, which isfixednpon shaft 5, having through the intervening lugs of theintervening clips acted upon arm 34 to raise it to the position shown insaid Fig. 8, which disconnects the hook 40 from the rod 49. The pocketsare sufficiently supported while all are at their normally highestposition by the latch 41, held in the position shown by the link 35, arm36, shaft 37, and lug 51, fixed upon the shaft. When one of the pocketsis withdrawn from the latch 41 and lowered, as shown in the right-handside of Fig. 1, a rotary movement is at once communicated to shaft 5,which moves the clip-lugs in a direction to separate the same from eachother and permit the arm 34 to drop, thereby permitting the hook 40 toalso drop and engage the shaft 49 of all the pockets which are allowedto remain at their normally highest position and lock the same in suchposition, so that there will be no danger of their falling out upon aperson while operating a neighboring pocket, the object being to securea positive locking device for the remaining pockets, in addition to thelatches 41, while any one pocket is being'operated' to the exclusion ofthe others.

The oscillatory arms not only serve to support the pockets when in theirnormal position, but also serve to deflect the pockets and theirsupporting-cables from the plane of its support when in its normalposition to a plane wholly outside of the supporting-pivot 46, the twopositions being indicated by solid and dotted lines in Fig. 2.

(Shown by solid The counterbalance is intended to be of the proper.weight to balance one of the storagepockets at a time, together with itsaverage load, and if a large part or all of the load or' contents of thepocket should be removed from the pocket when in the position shown bysolid lines in Fig. 2that is, at a lower level-the empty pocket would beoverbalanced vand forced upward unless positively locked in someposition. As ameans forlocking the pocketin a lower level I provide anotched disk 60, loose on shaft 5 and secured from turning thereon bythe link 61, rigidly connecting the- The arm 62 is provided with dog 64,pivoted thereon at65 and adapted to enter the. notch 66, as shown inFig. 6, and thereby lock the arm and disk relatively to each other; butthe arm being fastened to the shaft 5 and the disk to the case the shaftis prevented from turning in a direction to permit the pocket-to rise.As a means for unlocking this mechanism, so as. to permit the pocket tobe raised or moved .upward, the disk is provided with a projectingfinger 67, up which the dog 64'rides before reaching the notches 66. Tounlock-the parts, it is only necessary to move the pocket a littlefarther downward, which will move the dog 64 back to the left of finger67, as shown in the drawings, then quickly move the pocket in theopposite direction, which will cause the dog to jump over the finger andpast the'notch into the level surface 68, and so on past the notch, andto prevent the dog from again engaging with the notch until the pockethas been restored to its normal position a loose thin sheet -'metal arm7 O is loosely mounted upon shaft 5 between the disk 60 and arm 62, andthe arm 62, provided with the projecting lug 71, adapted to engage thearm 7 0, so as to keep one just in advance of the other while going inthe direction taken when the pocket is traveling upwardly. This arm 7 0is-so shaped on its oscillatory end as to prevent the dog 64 fromengaging the notch 66, as seen in Fig. 7. WV hen any of the pockets arepulled down from their normal position, the revoluble movement of arm 62is reversed, which causes the lug 71 to pass around shaft 5 and engagearm on the side opposite to that sidewith which the lug is shown inengagement in Fig. 7, which forces the arm 7 O away from notch 66,leaving it open to be engaged by dog 64. When the counterbalance and theloaded pocket are about evenly balanced, the pocket can be easily andsteadily moved from a lower to a higher position; but as it approachesits normal position during the later part of its movement, when it ispartly supported by the oscillatory arm 45, it moves in an approximatelyhorizontal direction, so that its weight is greatly over-balanced by thecounterbal- IIS , vided for retarding its/motion.

ance, and its later movements would be rapidly accelerated if some eanswere not pro- I As a means for accomplishing this result I provide agovernor mechanism consisting of a bracket 80, fixed upon the case-frameby means of the screws 81 and provided with a worm-thread 83, adapted tobe engaged by telith on the toothed wheel 84, fixed upon to rotate withshaft 5, whereby rotary movements of the shaft cause a much more rapidmovement of the spindle 82. To the upper end of the spindle 82 are fixedthe ordinary governor balance or weights 85. Theoutward movement of theweights forces downwardly the sleeve 86 and causes the same tofrictionally engage with the stationary surface 87 on thebearing-support,'the neighboring surface of the sleeve andbearing-support being enlarged, so as to afford a considerable engagingsurface. The friction of the rotating sleeve 86 on the stationarysurface 87 retards the rotary movement of the wormi-spindle, andconsequently of the shaft 5. As a means for allowing the shaft 5 to turnin the opposite direction when the pocket is descending I make thetoothed wheel 84 loose upon shaft 5 and provide means for connectingit'when moving in one direction with the hub 88, fixed upon shaft 5 bymeans ofthe dogs 89, pivoted upon the hub and adapted to fly outward bycentrifugal force when the shaft 5 is rapidly rotated and engage notchesin the loose toothed wheel,

which immediately puts in operation the governor-balls. The dogs arenormally held out of engagement with the notches by means of the lightcoil-springs 90.

I also provide bufiers to take up the shock caused-by the suddenstoppage of the pockets when they reach their normal positions, whichmaybe of any known form ofconstructionas, for example, an uprightspring-bar 93, secured to the case-frame at its middle by the pin 94,its lower end bearing against the frame and its upper end adapted to beengaged by the guide-pulley 50.

I also provide means for assisting an upward movement of aheavily-loaded pocket consisting of a drum 100, fixed upon shaft 5 andprovided with a cable 101, adapted to wind thereon and having one endsecured thereto, the other end of the cable passing out through anaperture 102 in the case-wall and over the loose pulley 1-03, supportedby ear-brackets 104, secured to the frame-case,

the outer end of the cable being provided with a suitable handle 105. Bypulling down upon the handle a rotary movement will be given to shaft 5,which will raise the pocket.

What I claim as new, and desire to secure by Letters Patent, is- T 1. Aplurality of movable storage-pockets in combination with acounterbalance; and means whereby the pockets can be moved up and down,one at a time; and means for actively connecting the pockets, oneat atime,
